Research and Design on Network Topology Management System of EJB Clustering

This paper analyzes some approaches to manage the network topology of EJB clustering, and presents a Network Topology Management System that based on shared global JNDI, including overall design for this system and detailed design for some key technologies. The Management of network topology is a submodule of cluster service, and it makes the cluster system have two important features: flexible scalability and high availability. Besides, this paper not only emphasizes on portability and extensibility of the system but also completes the collect of load information in the design procedure, so it is easy to expand this system and then integrate the system to J2EE application server.
